Sweden Enea strengthened its Polyhedra relational database management system (RDBMS) family by developing version 7.0. Polyhedra 7.0, a fault-tolerant, in-memory, transactional RDBMS, is available in 32-bit and 64-bit versions and provides a secure data repository for network infrastructure applications. It also features journaling and fault-tolerant mechanisms including instant failover and fast reconnection that ensure data persistence. This management system is suitable for carrier-grade network infrastructure systems, particularly those utilizing distributed applications and data spread across multiple processors, blades and operating systems.
The RDBMS uses a client-server architecture that enhances performance and simplifies distributed application design, particularly for systems utilizing heterogeneous hardware. It also improves data integrity and resilience by separating the data from the applications that use it, thereby protecting the memory used by the database software from accidental modification. Active queries provide a fine-grained SQL push technology that notifies applications of data changes as soon as they occur. This eliminates the need for polling, thereby reducing processor usage. Polyhedra also lets the database designer set up active, triggered, database-resident code, which enables application-level data integrity rules to be built into the database. Polyhedra 7.0 can be used in operating systems including OSE, VxWorks, Integrity, Linux, Windows and Unix.
